EM330 3-Phase Energy Meter
Three-phase energy meter with backlit LCD display with integrated touch keypad. Particularly indicated for active energy metering and for cost allocation (CT connection), with dual tariff management availability.
It can measure imported and exported energy or be programmed to consider only the imported one. Housing for DIN-rail mounting, with IP51 front degree protection.
The meter is optionally provided with pulse output proportional to the active energy being measured, RS485 Modbus port or M-Bus port. Available for legal metrology (PF option, only for imported energy).
